Abstract: The problem addressed by the invention is that of simplifying a conversion of the gutter system of an IS machine, for example, from double forming operation to triple forming operation and vice versa. This problem is solved in that a guide plate assembly (80) is provided in the course of the sliding path for molten glass drops, which guide plate assembly consists of a first assembly, which is composed of an elongate base (26) intended to be fastened to a scoop beam (21) and of supporting segments (29, 30) attached to said base, and a second assembly, which is composed of a guide plate unit (22) designed as a direct support of guide plates (42) and intended to be mounted on the first assembly. A conversion in the aforementioned sense can be limited to a replacement of said second assembly, whereby a significant reduction in assembly activities and set-up activities can be achieved.

The mold holders (4, 5) are mounted on a linear guide and are joined with a threaded spindle, threaded sleeve and gearing with a drive set up on the outlet side for generating a vertically oriented linear movement. A toggle-lever mechanism situated inside of an oil bath accommodated in the station housing (1) is used as the gearing. This arrangement of essential components of the drivetrain opens allows removal of the drivetrain via the upper side of the station housing when necessary or incorporating the drivetrain into the station housing, thereby simplifying repair and maintenance work.

Abstract: In order to achieve reproducible operating parameters of the shaping process of an I.S. glassware forming machine, a central control of all blowing and cooling air flows is proposed, in which in accordance with sections a volume flow of the cooling air including the inlet-side and outlet-side temperatures thereof are measured by means of a measuring device (51, 52) and a heat loss which is associated with the section is ascertained. The heat thus removed in sections is compared with standard values, wherein in the event that tolerance zones are exceeded a variation of the volume flow is initiated by the actuation of restrictors (53, 54). All of the sections of the glassware forming machine which are intended for passage of cooling air are monitored in this way, namely on the basis of a determinable heat loss, so that uniform cooling conditions, which are adapted to a mathematical model, and in this respect a reproducible product quality are achieved.
